The SSL/TLS protocol is the bedrock of online secure communications and is generally assumed to provide a high level of security. However, like other cryptographic protocols, its strength is dependent on the quality of the random values used to initialize it. Here we investigate the quality of such values across 2.5TB of captured internet traffic. We observed large numbers of repeating values, with significant counts. After some analysis we conclude that though the sources of some of these values are insignificant, there do exist a substantial number of broken implementations that are contributing to a cryptographic ecosystem with significant insecurities.
